Abstract

Acid dyes are toxic pollutants and known to be carcinogenic and harmful to organisms even at very low concentrations. Strict legislation governing the release of these harmful chemicals demands the development of a variety of effective techniques for removing organic contaminants from wastewater. The present study was undertaken to remove acid red dye using a hybrid material composite of Li/TiO₂ – waste powder of marble (WPM) industry which acts as both photocatalyst and adsorbent. The effect of various operational parameters including pH, dose, initial dye concentration, and time was optimized during the present study. The adsorbent material used was found very effective in dye removal.

Keywords: acid red dye, adsorption, photocatalysis, pH, dose
